(54) Low particulate liquid filling machine and method


(57) An improved automatic bottle filling apparatus is provided. The apparatus includes a spring loaded back pressure plate (56) which avoids jamming of bottles (19) that are carried by conveyor (11). A bottle detection system comprising a photoelectric device (65) or microswitch (70) assures positioning and detection of an individual bottle. Vibration is essentially dampened by guide plates (38) and (39) riding on vertical columns (36) and (37). Overheating of the drive motors to operate the vertical movement (11) is obviated by use of a pair of continuously operated motors (25) and (26) running in opposite directions connected to mechanical actuators (29) and (30) by means of clutch brake mechanism (27) and (28).
